“…While the increased amount of organic matter in soil increases microbial growth, biochar addition significantly reduces soil NO 3 − -N content (Mulabagal et al, 2022). Some studies have reported increases in soil microbial populations following biochar addition (Aboughaly and Fattah, 2023), while others have observed no significant change (Bamdad et al, 2022) or even a reduction (Saleem et al, 2022) in microbial populations.…”

“…Biochar can directly and indirectly affect soil microbial populations (Mulabagal et al, 2022). Due to its higher aromatic hydrocarbon structure, biochar provides a conducive environment for soil microorganisms such as fungi, bacteria, and algae, which benefit from the nutrients and habitat created by biochar (Aboughaly and Fattah, 2023).…”

Biochar production and application have become increasingly popular in the past 15 years. Biochar, derived from diverse biomass types, offers a rich carbon source created through thermal combustion. Biochar production primarily depends on pyrolysis conditions and feedstock type. This review focuses on the multifaceted aspects of biochar, encompassing hydrothermal carbonization, gasification, and pyrolysis temperatures in biochar production and its role in bioeconomy and soil remediation. Biochar has yielded valuable insights, notably in decreasing nutrient leaching, curbing greenhouse gas (GHG) emissions, reducing the bioavailability of environmental pollutants, sequestering carbon (C) in soils, and enhancing agricultural productivity. Consequently, it has emerged as a valuable commodity for the bioeconomy, which involves harnessing bioresources through bioengineering to create economically valuable products. As a marketable output, biochar finds application in energy, diverse biochar-based product manufacturing, and the agricultural sector. Thus, biochar production not only enhances soil quality but also unlocks additional revenue streams. This review underscores the critical role of feedstock selection and pyrolysis conditions in optimizing biochar production. Furthermore, it highlights biochar as a sustainable and effective tool for improving various soil types and remediating soil contamination caused by organic impurities, including persistent organic compounds and antibiotics.

“…Thus, if biochar is applied to soil, it can increase soil carbon sequestration [54]. Biochar derived from the pyrolysis of agricultural residues is a potentially viable strategy for developing negative carbon emission technologies for climate change mitigation change and a material for effective amendment of relatively poor soils to improve their quality and fertility [55]. The pyrolysis system of agricultural residues for biofuel production and carbon sequestration is shown in Figure 7.…”

China is encountering two big challenges: supply shortage of energy especially liquid fuels and serious environmental problems especially increasing CO 2 emissions. Agricultural residues are readily available and inexpensive renewable resources in China and it can be expected to reduce China's reliance on fossil fuels and CO 2 emissions through the use of agricultural residues. This study conducted a systematic study of energy production and consumption, CO 2 emissions, and agricultural residues available for energy and environmental bene ts. The gap between the domestic production and consumption of energy in China became larger and larger, and China's energy consumption structure was dominated by coal over the past thirty years. The increasing energy consumption especially coal consumption were strongly linked the increasing CO 2 emissions in China. As the largest agricultural country in the world, China has abundant agricultural residues, most of which were utilized as soil amendments, animal feeds, substrates in mushroom cultivation, and industrial materials. The usable agricultural residues for energy were estimated to be about 226.9 million tons in 2020. If those usable agricultural residues would be converted into bio-oil and biochar through pyrolysis, it could not only replace about 102 million tons of crude oil, but also sequestrate about 209 million tons of CO 2 -equivalent. It is expected that the results from this study can promote the application of agricultural residues in potential of energy production and carbon sequestration. Statement of NoveltyIn this study, the energy production and consumption, CO 2 emissions, and pyrolysis conversion of agricultural residues resources for energy and environmental bene ts in China were comprehensively investigated. The highlights are listed as follows: (1) Gap between energy production and consumption in China became larger and larger; (2) CO 2 emissions has signi cantly increased by three times during the past three decades; (3) Total collectable agricultural residues annually reached 0.96 billion tons; (4) Usable agricultural residues for energy annually reached 227 million tons; (5) Pyrolysis of agricultural residues is effective for energy and environmental bene ts.

“…Biochar holds the promise of being a game-changer in the field of carbon credits and climate change mitigation [12]. Biochar, a form of charcoal, is the product of the conversion of organic materials, such as agricultural waste and forestry by-products, into a stable form of carbon that can be stored in soils for centuries [13].…”

The creation of the carbon market came forth as a tool for managing, controlling, and reducing greenhouse gas emissions, combining environmental responsibility with financial incentives. Biochar has gained recognition as one of potential carbon offset solution. The practical and cost-effective establishment of biochar carbon credit standards is crucial for the integration of biochar into carbon trading systems, thus encouraging investments in the biochar industry while promoting sustainable carbon dioxide sequestration practices on a global scale. This communication focuses on the potential of biochar in carbon sequestration. Additionally, it spotlights case studies that highlight how biochar effectively generates carbon credits, as well as discussing the evolving carbon removal marketplace. Furthermore, we address knowledge gaps, areas of concern, and research priorities regarding biochar implementation in carbon credits, with the aim of enhancing our understanding of its role in climate change mitigation. This review positions biochar as a versatile and scalable technology with the potential to contribute significantly to carbon credits, aligning with sustainable development goals. It calls for continued research, transparency, and international cooperation to explore the full potential of biochar in climate change mitigation efforts.
